If we did want to have an "everyone works together" atmosphere, here's a mod that might help with that: The Invasion Mod. We could build a whole compound, or even multiple bases, and place a Nexus in each one. Sound interesting?

EDIT: It turns out that I cannot add mods with the current server plan that I am using. I guess that's what I get for taking the cheap plan . Maybe I'll look into upgrading the server in the future, but right now I think that I'm going to stay put.
